4 Reasons Why Your Furnace is Shutting Off Your Circuit Breaker and How to Solve It

Tripped circuit breakers are frustrating and troublesome, particularly if it seems like the furnace is the cause. If your breaker gets thrown once and typical function returns after you reset it, there is no abrupt cause for concern. In this situation, a surprise power surge is typically the source.

However, you can’t avoid the situation if the breaker gets thrown repeatedly. This might happen with both electric and gas furnaces. After all, even gas-fired furnaces utilize electricity to run the blower motor and other parts. Before you request furnace repair, consider the most common reasons your furnace could be tripping the circuit breaker and how you can handle it.

1. Overheated Furnace

Does your furnace run for just a few minutes before flipping the breaker? This may be a result of restricted airflow. A dirty filter or closed air vents require your furnace to work harder. The increased electrical draw might overheat the system, strain the circuit andthrow the breaker. Here are some tips to restore consistent airflow and resolve the problem:

  • Change the air filter.
  • Open all air registers and make certain none are restricted by furniture, curtains or rugs.
  • Don’t leave anything against the furnace or otherwise block airflow into it.

2. Overloaded Circuit

HVAC equipment should be on a dedicated circuit, but this may not be the case in older houses. Examine the labels on your electrical panel to find out if another appliance shares a circuit with your furnace. As a brief resolution, you can unplug the secondary item or avoid operating it while the furnace is on. A wiser, more lasting solution is to have an electrician install a dedicated circuit for your HVAC system.

3. Short Circuit or Ground Fault

Does your furnace trip the circuit breaker right as it begins running? This may be evidence of an electrical problem within the furnace. An exposed wire could be shorting out the circuit when it touches a neutral wire or leads to a ground fault if it meets a grounded wire or metal object. Either of these things can affect the electrical draw enough to flip the circuit. You’ll need an HVAC specialist like Service Experts Heating & Air Conditioning to find and resolve the trouble.

4. Electrical Panel Issue

If you rule out any trouble with your furnace, the electrical panel might be to blame. Poor connections or malfunctioning breakers will sometimes lead to inconsistent performance. If you have an older home, you may need to have the panel replaced if it’s outdated, damaged or incorrectly installed. In this instance, you need the expertise of an electrician.
